Symptoms
-
When clicking the Secure button in Plesk at Domains > example.com > Check Security nothing happens: There is still a red exclamation mark next to Permissions for files and directories.
- Unable to apply security measure "Restrict access to files and directories":
Unable to set permissions on /var/www/vhosts/example.com/httpdocs/script.php: Operation not permitted
Cause
Incorrect ownership on files/directories under a domain document root directory.
Resolution
Files/directories under a domain document root directory should belong to psacln group and to the sysuser user. Set the correct ownership as follows:
-
Connect to the Plesk server using SSH.
-
Modify the ownership for all files and directories inside domain's document root:
# plesk repair fs -y example.com
Note: the solution above is applicable for Plesk 17.8 and Plesk Obsidian. For other versions use the solution from this article: How to restore default permissions in the virtual host directory on Linux
